A garden planner built around the year

What makes it different?

Most garden planning software concentrates on the hard landscaping, the structures and the layout of the plot. The plants are often there as decoration. In Seasonry the plants are what everything is built around.

• Everything is drawn to scale, in real metres.
• Plants appear at the size they will reach when grown, not as simple symbols.
• You can look at the garden in every month of the year, so you see not only when it is at its best but how it changes as the year goes on.
• The catalogue holds more than 2,000 plants, each with its sun, water, soil and damp needs in detail.
• The sun-path and shadow simulation shows how the light in the garden changes through the day and through the year.

What is Seasonry?

Seasonry helps you think your garden through and plan it before you plant it.

First you draw the outline of your plot, then you place the beds, paths and other garden elements at the size they really are. After that you pick the plants from the catalogue and put them where you want them.

Every plant takes up as much room on the plan as it will when it is grown, so you can see in advance what fits beside what, how much space each one will need later, and how the garden will look as a whole.

Seasonry runs straight in a web browser, on a desktop or a laptop.

Why we built it

Seasonry started with a problem of our own.

A few years ago we moved into a house with a garden, and we wanted to make something good out of it. We soon found that planning a garden is about far more than picking the plants you like.

We had to know how big each plant would grow, and how far apart to plant them so they would still have room in a few years. Even finding that out was not easy, and we could not find a garden planner that showed the plants, and the way a garden changes, the way we wanted to see them.

At first we drew circles of different sizes on paper where the plants would go. As programmers, it was a short step from there to building our own version out of curiosity. That is how Seasonry started.

The more we used it, the more questions came up. Friends, family and colleagues suggested things, but many features simply came out of running into another problem while planning our own garden.

When will the bed be in flower, and what will be flowering?

That is where the Bloom calendar came from.

What happens when we go away? How do we show the person doing the watering which plant is where and how much water it needs?

That became Vacation Mode.

Is this a good spot for a plant? How much sun will it get in spring, in summer, in autumn?

That grew into the sun-path and shadow simulation.

Which plants cope better with long dry spells, and which suffer most when water is short?

The 2026 heat dome hit our own garden hard. That was when it became important to us to see not only how much water a plant wants, but how well it copes without it. That is where the Water panel came from, which helps you see which plants are the more drought-tolerant ones and which are the more sensitive to a long dry spell.

And we could go on.

That is how Seasonry has kept growing ever since: a real gardening question or problem turns into a new feature.

One thing stayed important to us throughout: that you should be able to plan more than how the garden looks on a fine summer day.

We wanted to build a garden planner that shows the whole year. So before you plant anything you can see when the bed will be in flower, which stretches may be quieter, how the light changes, and where the plan is still worth adjusting.

Who it is for

Home gardeners planning a new bed, a border, or a whole plot from scratch. It assumes no training in landscape design and no drawing skill: if you can drag a shape, you can lay out a garden. The plant data is chosen for dry continental gardens, so it is most accurate in central Europe, but the planning tools work anywhere.

Languages

Seasonry is made in Hungary and published in English and Hungarian. Both are complete rather than partial: the interface, the plant names, the lessons and the help pages are all translated, and you can switch language at any time.

Free and paid

Seasonry is free to start, and the free plan includes the whole catalogue and every plant’s growing conditions. Seasonry+ adds the seasonal view, the sun path and its shadows, the Bloom calendar, the Water panel, bed matching, automatic planting and Vacation Mode with its shareable watering plan. The current limits and prices are on the pricing page.
